Platform competition in NYC ride-hailing wastes $176M/yr and 21% of driver traffic. A merger would cut traffic by 8% but raise prices, costing consumers $77M/yr. Interoperability rules could reduce traffic by 6% and boost consumer surplus by $63M/yr. buff.ly/MeV4sJz

U.S. municipal bonds remain illiquid; this article links this illiquidity to underwriter-driven complexity and quantifies the welfare gains from mandating standardization. buff.ly/KfH7vsT

We show a long-run player who repeatedly observes private signals and takes actions can sometimes establish a reputation even when their strategy is not identified. Our result applies to games of deterrence, delegation, signaling, and Bayesian persuasion. buff.ly/NcrNE6L

Could a highly desirable agent accept a partner that a less desirable agent would reject? When matching requires search in time-changing environments, this paper proves this impossible only where more desirable agents are more patient and less risk-averse. buff.ly/S5uwd3j

Analyzing scientists' biographies during the baby boom, we find that mothers have a unique life cycle pattern of productivity. Children reduce the productivity of mothers but not fathers, with important implications for promotions and participation. buff.ly/39WbYRH
